desc:
  OpenPAM is an open source PAM library that focuses on simplicity,
  correctness, and cleanliness.
  
  OpenPAM aims to gather the best features of Solaris PAM, XSSO and
  Linux-PAM, plus some innovations of its own.  In areas where these
  implementations disagree, OpenPAM tries to remain compatible with
  Solaris, at the expense of XSSO conformance and Linux-PAM
  compatibility.
